The meridian 15° west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Greenland, Iceland, the Atlantic Ocean, Africa, the Southern Ocean, and Antarctica to the South Pole.

Technically -1 hour.......so 9:00am.......but all countries on that line are running on GMT....so it’s same 10:00am there....

sanjay sold an article at a loss of 25 percent if the selling price had been increased by rs 175.there would have been gain of 1

vagabundo [1.1K]

Answer:

The cost price is Rs.500

Explanation:

<em>I'll approach this question by taking the statements in the question, one after the other</em>

Let the cost price be represented by CP

From the first statement:

Sanjay made a loss of 25%

The selling price (SP) is as follows;

$SP = CP - 25\% * CP$

Convert percent to fraction

$SP =CP - \frac{25}{100} * CP$

Get decimal equivalent

$SP = CP-0.25 * CP$

$SP = CP - 0.25CP$

$SP = 0.75CP$

From the second statement:

If the selling price was increased by 175%, Sanjay would make a profit of 10%

Hence; The new selling price is

$SP = 0.75CP + 175$

The selling price can also be calculated from the profit

$SP = CP + 10\% * CP$

Convert percent to fraction

$SP = CP + \frac{10}{100} * CP$

Get decimal equivalent

$SP = CP + 0.10 * CP$

$SP = CP + 0.10 CP$

$SP = 1.10 CP$

Equate both values of SP (SP = SP)

$1.10CP = 0.75CP + 175$

Collect Like Terms

$1.10CP - 0.75CP = 175$

$0.35CP = 1.75$

Divide both sides by 0.35

$CP = \frac{175}{0.35}$

$CP = 500$

<em>Hence, the cost price is Rs.500</em>

How do we know there is Dark Matter in other galaxies? a. it occasionally lum inesces b. flat rotation curves in spiral galaxies

lesantik [10]

Answer:

b. flat rotation curves in spiral galaxies

Explanation:

Dark matter accounts for majority of the matter in the universe (about 85%). It is considered to be composed of subatomic particles which are yet to be discovered. Dark matter cannot be observed because it does not emit light that can be detected. Only its gravitational effect is visible.

Astronomers when calculated the mass of the visible matter and tried to account for the observed speed of stars in the galaxy, there was a mismatch. To understand what caused this mismatch, astronomers gave name to the invisible matter as the Dark Matter.

The expected velocity of stars should decrease away from the near the center of the galaxy but a constant velocity of stars was observed that is a relatively flat rotation curve was obtained.

Thus, flat rotation curves in spiral galaxies in an evidence of Dark Matter.
